(b) What percentage of organs weighs between 230 grams and 370 grams?

Which of the following is the equation of the graph shown below?
A. f(x) = −4sin(x)
B. f(x) = −4cos(x)
C. f(x) = 4cos(x)
D. f(x) = 4sin(x)
Answer:
a
Step-by-step explanation:
since cosine 0 is 1 leading to the elimination of both c and b.
sine starts out positive and goes negative after π however the graph shows the opposite leading the answer to be a
Answer:
A. f(x) = −4sin(x)
Step-by-step explanation:
The graph that meets the origin and goes down is option A, f(x)=-4sin(x). This is because the sine function oscillates between 1 and -1, and the negative sign in front of the sine function flips the graph upside down. So, the graph starts at the origin at a value of 0, then oscillates down to a minimum value of -4, then oscillates back up to a maximum value of 4, and so on.

A model rollercoaster is built to a scale of 1:32. In the model rollercoaster, the angle between the ground and the steepest slope is 110°. What is the angle between the ground and steepest slope on the real rollercoaster?
The angle between the ground and the steepest slope on the real rollercoaster is approximately 89.998°.
A model rollercoaster is built to a scale of 1:32. In the model rollercoaster, the angle between the ground and the steepest slope is 110°.What is the angle between the ground and the steepest slope on the real rollercoaster?
To determine the angle between the ground and the steepest slope on the real rollercoaster, you need to consider the scale of the model rollercoaster.To find the real rollercoaster angle, you should use a scale factor that relates the model rollercoaster to the real one.
The scale factor should multiply the model angle to obtain the real one. Since the scale factor relates the model length to the real length, it should relate the horizontal distance and the vertical height.
The horizontal and vertical lengths are in a ratio of 32:1 for the model. This means that for every 32 units in the model, there is one unit in the real rollercoaster. Therefore, we can say that the horizontal length of the real rollercoaster is 32 times the horizontal length of the model rollercoaster.
That is:h(real) = 32h(model)Similarly, the vertical height of the real rollercoaster is 32 times the vertical height of the model rollercoaster. That is:v(real) = 32v(model)
The tangent of an angle equals the vertical height divided by the horizontal distance. Therefore, the tangent of the real angle equals the tangent of the model angle times the scale factor.
That is:tanθ(real) = 32tanθ(model)By substitution,θ(real) = arctan(32tanθ(model))For the given model angle of 110°,
the corresponding real angle is:θ(real) = arctan(32tan110°)θ(real) = arctan(32(-2.74747741945462))θ(real) = arctan(-87.91927694142864)θ(real) ≈ -89.998°
The negative sign indicates that the angle is measured below the horizontal line.

Solve for x.
5 = 3x - 3
Answer:
x = 8/3
Step-by-step explanation:
Step 1: Write equation
5 = 3x - 3
Step 2: Solve for x
Add 3 to both sides: 8 = 3xDivide both sides by 3: 8/3 = xRewrite: x = 8/3Step 3: Check
Plug in x to verify it's a solution.
5 = 3(8/3) - 3
5 = 8 - 3
5 = 5
Answer:
x= [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
5=3x-3
first, add 3 to both sides:
5 +3 = 3x-3 +3
8=3x
then, divide both sides by 3:
8 ÷3 = 3x ÷3
and the answer can be written as x = [tex]\frac{8}{3}[/tex] or x = 2[tex]\frac{2}{3}[/tex]

Answer: Sum of 180˚
Step-by-step explanation:
Hence, the supplement of a 20˚ angle is a 160˚ angle. This can be proven again, since 20+160=180 , and supplementary angles have a sum of 180˚ .

Approximate 5.824 to the nearest whole
Answer:
The nearest whole is 6.
Step-by-step explanation:
We are going to round each number.
We know the rule if it is under 5, we do not make the number change. If it is above 5, the number changes. For this one, we do not have to round the hundredths or thousandths. We do round the 8, though. The nearest whole to 5.8 is 6, since 8 is above 5 and that means it is closer to 6 rather than 5.
Write and solve an inequality for the situation. Tom is deciding whether he should become a member of a gym to use the basketball courts. The membership costs $135. Then, members will pay $3 each time they rent out the courts. Nonmembers can also rent the courts for $11 each time. How many times would Tom have to rent the basketball courts in order for his cost as a member to be cheaper than the cost of a nonmember? As a member, Tom's cost would be cheaper if he rents the courts or more times.
Answer:
As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.
Step-by-step explanation:
Let the number of times be x
If Tom is a member, and rents the courts x number of times, then he would pay
$135 + $3 × x = $135 + $3x
For a nonmember that rents x number of times, the nonmember would pay
$11 × x = $11x
Now, we are to determine which value of x for which $135 + $3x is less than $11x, that is
$135 + $3x < $11x
Solving the inequality,
$135 < $11x - $3x
$135 < $8x
$135 / $8 < x
16.875 < x
∴ x > 16.875
This means, for Tom's cost to be cheaper, he must have rented the court for more than 16.875 times. (Round 16.875 to the nearest whole number)
16.875 ≅ 17
∴ x > 17
Hence, As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.

Help please i don’t understand
Answer:
AB ≈ 5.39
Step-by-step explanation:
If you draw a line down from A, and another line left from B, the lines will intersect to form a right triangle with AB as the hypotenuse. You can use the Pythagorean theorem to find the length AB.
The vertical leg is 2 grid squares (units) long. The horizontal leg is 5 grid squares (units) long.
Then the hypotenuse, AB, is ...
AB = √(2² +5²) = √(4 +25) = √29
AB ≈ 5.39
The length of AB is about 5.39 units.

a.
$4,342
b $5,513
$5,679
d $13,863
$5,679.16 interest is earned on the investment
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
P = $8,350 the principal (the money deposited)
r = 0.052 or 5.2% annual interest rate
t = 10 years
m = 12 compounding period per year
i = r/m = 0.052/12 = 0.013/3 interest rate per period
n = t×m = 10×12 = 120 total number of compounding periods
A = future value
A = P(1 + i)ⁿ
A = 8350(1 + 0.013/3)¹²⁰
A = $14,029.16
I = A - P
I = 14029.16 - 8350
I = $5,679.16
there are $5,679.16 interest earned on the investment.
Hence, $5,679.16 interest is earned on the investment

1. Find two numbers with a common factor of 3 only.
2. Write a pair of numbers with a common factor of 2, 3 and
6.
3. Write a pair of numbers with common factors of 3, 6 and
9.
Answer:
All numbers can be written as a product of the prime numbers that conform them.
A) Find two numbers with a common factor of 3 only.
for example:
2*3 = 6
7*3 = 21
Both numbers have the factor 3 in them, and because the other two numbers are primes, we can be sure that the 3 is the only common factor.
B) Write a pair of numbers with a common factor of 2, 3 and 6.
Here we can write:
2*3*2 = 12
3*2*5 = 30
Those two numbers have the common factors 6, 2 and 3.
C) Write a pair of numbers with common factors of 3, 6 and 9.
3*2*3 = 18 (has the factors 2, 3, 3*2 = 6, 3*3 = 9)
-3*2*6 = -36
Both have the common factors 3, 6 and 9 (and they share more common factors like 2, this happens because 6 = 3*2, so if 6 is a common factor, 2 also must be)
